Compared to the boom of 1950 to 2000, you can't expect the same exponential growth in cars, people, consuming etc in the 2000-2050 sector.
Not entirely true in my opinion.
The 1950-2000 brought about a lot of fluctuations in consumption and so on. Many economies were beginning to diverse and revolutions brought about issues for a lot of the world. Now however, certain countries are massively growing in population size and the economy is a lot more settled than it was then - oil production and consumption will only keep rising unless govt. initiatives are started.
